by Atomic Mass
The elements arranged according to their atomic number in the table are called periodic table.
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
before it there was no organization, but the first periodic table was organized by atomic mass.
In the periodic table, the elements are arranged by atomic number
The periodic table was first arranged by Dmitri Mendeleev in 1869. He organized the elements by increasing atomic mass and grouped them based on similar chemical properties. Gaps were left for undiscovered elements, with their properties predicted based on neighboring elements.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
All of the known 118 naturally occurring and synthetic elements are arranged on the periodic table.
Elements are arranged by their atomic number. The properties are periodic when arranged in this manner.
Dmitri Mendeleev first periodic table is called Mendeleev's periodic table. Elements are arranged according to atomic mass.
By Atomic Mass
some guy called Mendeleev
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
